LYNN'A. WILLIAMS, OF EVANSTON, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO WILLIAM R. HEATH, OF BUFFALO, NEW YORK.

ACCOUNTING SYSTEM.

To all whom it may concern:

Be it known that I, LYNN A. WILLIAMS, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Accounting Systems, of which the following is a full, clear, concise, and eXact description, reference be-. ing had to the accompanying drawings, forming a part of this specification.

My invention relates to an improvement in accounting systems and has special reference to a method whereby, when there is a mechanical system for accounting for a workmans wages, a waste-wage register will be actuated when he is not employed on a specific job, and on being assigned to a job the actuation of the waste-wage register ceases at the instant when the actuation of the jobregister begins.

The most satisfactory method of accomplishing the result analogous to that described above has been according to the sys tem outlined in my copending application Serial No. 474,323, where an electro-mechanical system is used. A plug seat switch is employed, whereby when the plug is in its normal position an electrical connection is made in such manner that a waste-wage register is brought into the same circuit with a wage-register, and the two are actuated atthe same rate. Associated with the wageregisters and the waste-wage registers is a series of job-registers actuated by electromechanical means. Vhen a plug is withdrawn from its plug seat and inserted in a jack associated with any given job-register, the actuating mechanism for said register is brought into circuit with the actuating mechanism for the wage-register of any individual workman. On withdrawing the plug from its plug seat, the circuit with the waste-wage register is broken. It is therefore evident that the waste-wage register and the job-register cannot be actuated at the same time. If, when the plug is withdrawn from the plug seat, it'is not inserted immediately in the jack associated with any job-register, neither the waste wage register nor the job-register will be actuated, 211". though, of course, the actuation of the wageregister continues.

My present invention is adapted to obviate this diiiicult-y. Associated with each wastewage register is a switch, which in its nor- Specification of Letters Ifatent.

mal position makes connection with a circuit in which the wage-register of any given workman is included. Associated with this switch in an electromagnet, which on being energized attracts the switch, which acts as an armature, thereby breaking the circuit with the actuating mechanism for the wastewage registen Each workman hasa plug supplied with suitable conductors in such manner that on insertion in a jack associated with any job-register, the actuating mechanism of such register is brought into the same circuit with his wage-register. At the same time the insertion of the plug actuates the electromagnet associated with the switch which is adapted to include the waste-wage register in the same circuit, and by such energization the switch is attracted, thereby breaking such circuit. It now becomes clear that the possible difficulty mentioned in connection with my copending application, Serial No. 474,323, is entirely overcome in the present invention, as it is quite impossible that the waste-wage register associated with any wage-register should be thrown out of the circuit until the very instant that a jobregister is included in the circuit. The exact manner in which this result is accomplished will be described in detail hereafter.

In the accompanying drawings, Figure 1 is a diagrammatic representation of one embodiment of my system; Fig. 2 is a modified arrangement of the system, the totalizing arrangements being for the sake of clearness omitted; Fig. 3 illustrates a suitable form of electromagnetic register-actuating mechanism, and Fig. 4 shows a suitable form of difierential gearing that may be used when it is desired to totalize the actuations of certain registers. Fig. 5 shows in a diagrammatic view a means for causing impulses of current flow at different rates in accordance with the application above referred to.

Referring first to Fig. 1, 1 is a battery grounded at- 2, and having associated with its terminals the busses 3 and 4. The conductors 5 and 6 act as sources for electrical impulses of predetermined rates and may be connected, preferably in series, to wageregisters A and B, respectively. Each workman has a conductor, as 5 or 6, but for the point 9 is placed a switch blade 10, which is held in its normal position by a spring 11, contact being made with the conductor 12 at the point 13. The current flowing through the conductor 12 actuates the electromagnetic mechanism associated with the wastewage register VA, and then flows through the conductor 14 to the wire 15, and then to ground 16*. Associated with the switch blade is an electromagnet 7, one terminal of which is connected through the wire 8 with the bus 3. The other terminal is connected through the wire 29 to thesleeve of the plug (11,. Connected to the tip of the plug a is the conductor 30, which terminates in the contact 31. Connected with the sleeve contact of the jack 32 is the conductor 33, which leads to the conductor 26, which in turn connects with the bus 4 at the point 27. The tip contact of the jack 32 has connected therewith the conductor 34, which leads to the job-register J, the circuit for which is completed through the conductor 35 which leads to the ground 16a; through the conductor 15. The electromagnet 7, which is associated with the workman who has been assigned to register B, controls the circuit connections for the register B in the same way that the electromagnet 7 controls the circuit connections for the register A, and the parts associated with the electromagnet 7 are numbered the same as the corresponding parts associated with the electromagnet 7, except that the numbers are primed. Further description, therefore, of the associated parts of the electromagnet 7 will not be necessary. It will be observed that the plug a associated with the electromagnet 7 and assigned to workman No. 1, let us say, is in the out position. When workman No. lthat is, the workman who is as signed to the wage-register Aregisters in and his plug a remains in the out position, as, would be the case when the workman is not assigned to any particular job, the circuit through the register A will be closed across the switch contact 10 through the waste-register WA, as previously described. Let us now suppose that workman No. 2, who is assigned to wageregister B, has registered in and is assigned to some particular job so that the plug .7) is plugged into the jack 18. Current will then flow from the battery 1, conductor 3, conductor 22, through the winding of the electromagnet 7, conductor 24, the sleeve of plug 6, the sleeve contact of the jack 18, conductor 25, conductor 26, and back to the battery through conductor 4. The electromagnet 7 being thus energized, the armature 10 will be drawn away from the contact point l3 into engagement with the contact 31. This closes the circuit through the wage-register B and the job-register J? as follows: from the conductor 6, through the wage-register B, conductor 6, the point 9', switch-blade 10, contact point 31, conductor 17, the tip of the plug Z), the tip conductor of the jack 18, conductor 19, jobregister J conductor 20, conductor 15, and back to ground 16 As soon, however, as the plug 6 is withdrawn, the electromagnet 7- is deenergized, and the spring 11 draws the switch-blade 10 against the contact 13, thereby closing the circuit through the wage register 13 and the waste-wage register VB, as follows: the conductor 6, wage-register B, conductor 6, point 9, switch-blade 10, contact point 13', conductor 38, wage-register NB, conductor 39, conductor 15, and back to ground at 16 It will be clear from the above operation that a workmans wage-register must be actuated simultaneously with either a wastewage register or a job-register, when a wage-register is automatically disassociated from the other of those two registers.

In Fig. 2 I have shown another way in which the electromagnets control the association of the wage-registers with the Wastewage registers or the job-registers. In a way, this arrangement might be considered as a simplification of that shownin Fig. 1, in that it dispenses with one of the contacts, shown in F ig. 1 as associated with each relay.

Referring to Fig. 2, the winding of the electromagnet 7 is at one end connected with the main conductor 3, through conductor 40, and at its other end is connected by conductor 41 to the sleeve of the plug a. Similarly, one end of the winding of the electromagnet 7 is connected by conductor 42 with the main conductor 3, and at its other end is connected through the conductor 43 with the sleeve of the plug 1;. From the point 44 of the conductor 45 leads the conductor 46 to the switch-blade or armature 47 of the electromagnet 7. A spring 48 normally holds this armature against the contact 49, which forms the terminal of the conductor 12 leading to the wage-register A. The conductor 45 is connected to the tip of the plug a. From the point 50 of the conductor 51, which terminates in the tip of the plug 6, leads the conductor 52 to the switch-blade or armature 53 of the electromagnet 7 A spring 54 normally holds this armature against the contact 55, from which leads the conductor 38 to the waste-wage register VB, which is associated with the wage-register B. Considering that the workman assigned to the register A has registered in and that he has not been assigned to any particular job, so that his plug a will be in the out position, it will be seen that the circuit is closed'from the conductor 5 through the wage-register A, the conductor 45, to the point 44, then to conductor 46, the switchblade 47 contact 49, conductor 12, the wasteother side of the battery.

wage register WA, conductor 14, conductor 15, and back to the ground at 16a. As soon,

however, as the plug ais inserted in a jobjack, as would be the case if the workman were assigned to some specific job, the electromagnet 7 would be energized to break the circuit connection with the waste-wage register at the same time that the plug establishes connection with the job-register. In the illustration of Fig. 2, this is the case with the workman assigned to the register B and whose plug 5 has been inserted in the job-jack 18. The insertion of the plu 1) closes the circuit through the associated e ectromagnet 7 as follows: from the battery 1 to the main conductor 3, to conductor 12, through the winding of the electromagnet 7, conductor 43, the sleeve of the plug 5, the sleeve contact of the jack 18, conductor 25, conductor 26, conductor 4, and back to the The electromagnet 7 being thus energized will draw the armature 53 away from the contact 55 and break the circuit through the wage-register VB. Atthe same time the circuit through the job-register J 2 is closed as follows: from the conductor 6, through the wage-register B, conductor 51, the tip of the plug 5, the tip contact of the jack 18, conductor 19, jobregister J conductor 20, conductor 15, and back to the ground at 16a. Thus, precisely the same result is secured as with the arrange ment shown in Fig. 1. It will, of course, be evident that those skilled in the art might devise still further modifications as to the precise manner in which the electromagnets for controlling the connections of the wageregisters might be included in the circuit arrangements of my'system, without depart ing from the underlying idea of this invention.

To effect actuation of the registers any suitable form of actuating mechanism may be used. For the sake of illustration, I have shown in Fig. 3 a convenient form of device which may be electrically operated to actuate an associated register. As shown in that figure, a suitable electromagnet 56, adapted to be connected in the energizing circuit of the system, has associated there with an armature 57, which is carried by the arm or lever 58 pivoted at 59. The pawl 60 pivoted to the lever 58 has engagement with the teeth of the ratchet wheel 61. VVheneve-r the electromagnet is energized it will attract its armature and rock the arm 58 in a clockwise direction. This energization of the electromagnet is more or less only momentary, and as soon as the electromagnet is deenergized the arm 58 will be moved counter-clockwise by the spring 62. During this last mentioned movement of the arm 58 the pawl 60 will move the ratchet wheel 61 the space of one tooth. Upon the next energization of the electromagnet the pawl 60 will dro into the next lower tooth in order to give tlie ratchet wheel 61 another one-step advancement upon the deenergization of the electromagnet. This step-bystep movement of the ratchet wheel 61 is communicated to an associated register 63 by any suitable gear connection. In Fig. 3 I have shown the gear 64 rigidly connected with the ratchet wheel 61. The gear 6 1 meshes with the gear 65, to which is rigidly connected the worm-gear 66. This wormgear in turn actuates the worm 67 which is mounted upon the driving shaft of the register. Reverse movement of the ratchet wheel 61 is prevented by the locking-dog 68. It will, of course, be understood that the above described form of register-actuating mechanism has been set forth in this case merely for the sake of illustration, this mechanism forming in and of itself no part of my invention, and that any suitable form of device may be used in connection with each register to actuate the same electrically.

It is evident that if it is not desired to show the waste-wages of each individual workman, the register associated with the actuating mechanism may be omitted, suitable means being provided for totalizing the actuations of the electromagnetic mechanisms. A simple form of connection whereby the actuations of the registersas for instance the waste-wage registers WA and VVB, or the ob-registers J and J -may be totalized is illustrated in Fig. 4, which represent-s a side view of part of the mechanism shown in Fig. 3.

Referring to Fig. 4, it will be noticed that the ratchet wheel 61 and the gear 64: are

combined to form the central member of a sleeves 69 and 7 0, respectively. These side members are in engagement with the beveled pinion 71, pivotally mounted in the central member which rotates upon the shaft 72. The sleeves 69 and 70 are also rotatably mounted upon this shaft. At their farther ends these sleeves are provided with beveled gears 7 3 and 74, respectively, these gears forming each a side member of a differential set which forms part of the actuating mechanism of the next register in the series. These other differential sets have not been shown, for the reason that they are merely a duplication of the differential set, which is shown in Fig. 4, and would therefore be superfluous illustration.

It will be seen from Fig. 4 that the rotation of the central member causes rotation of the beveled pinion 71. If we suppose the sleeve 70 to be stationary, the pinion will impart the actuation of the ratchet wheel 61 to the gear 69 by traveling around the gear 70. If the gear 70 is being actuated by the central member of the associated mechanism, then the pinion 71 will be rotated at a rate proportional to the sum of the rates of actuation of the ratchet wheels which are operated by the electromagnets of the two adjacent mechanisms. In this way the actuations of the central members of the various difl erential sets are ultimately accumulated, to be transferred into a totalizing register, such as the registers WT or J T. WVith the precise arrangement as shown in Fig. 4, the normal direction of rotation of the central members of the adjacent diiferential sets would be alternately in opposite directions, so that the register-actuating mechanisms would have to be arranged accordingly. The difierential totalizing connections which I have shown in Fig. t do not in and of themselves form a part of my invention and have been set forth merely for the sake of illustration, and any other means may be provided for totalizing the actuations of certain registers if this is found desirable. However, so far as the operation of my system is concerned, such totalization is not essential. In the modification shown in Fig. 2, I have omitted the totalizing feature in order to promote simplicity in the drawing. I will here state that the register-actuating mechanism shown in Fig. 3 and the differential gear arrangement shown in Fig. 4 are fully set forth in the application of Arthur F. Poole, Serial No. 437,876, filed June 11, 1908.

In the case of the jobregisters, it is immaterial whether a job-register be associated with the workman, but it is desirable that the actuations of the mechanisms on a single job at which many individuals may be working should be totalized-as would be shown by the register JT in Fig. 1. It

is evident that if there are several jobs oneach of which several men may be working, the total for each job may be shown, these totals being again added to show the total wages of the several jobs.

As shown in Fig. 5, the current impulses required to actuate the registers proportionally to the wages paid the workmen, may be produced by the mechanism indicated diagrammatically which consists in a shaft 77 which has mounted thereon two cam disks 75 and 7 6. Switch springs 7 8 and 79 travel in cam grooves formed in the cylindrical surface of the disks and adapted when actuated by the cams to make and break contact with the contact springs 80 and 81 respectively. It is apparent that the conformation of the cam grooves determines the number of makes and breaks between the contacts in a given unit of time as the shaft 77 is caused to rotate continuously by any suitable means not shown. The contact springs 78 and 79 are connected together by the wire 82 which is in electrical connection with one terminal of the battery 1, the other terminal of which is grounded. The contact springs 80 and 81 are connected respectively with the wires 6 and 5 extending to the wage registers B and A.

By the above description I do not confine myself to the particular method of accomplishing the result herein described, as modifications may be made without departing from the scope of my invention.
